I have a hard non-movable lump on the right side of my neck about the size of a pinto bean. It feels like it may be attached to the larynx? I have been suffering from joint pain (knees, shoulders and right large toe) and swelling mainly in my knees. I seem to have lost strength in my knees due to swelling and muscle tenderness around joints, I am loosing more hair than normal, awful cramps in right callf at night, I get hot flashes but then I get cold and can t get warm, I have no energy, my skin is very dry to the point of tingling.
